IMPRovEo wRlNclNc-MACHINE.

Specification forming part of Letters Patent No. 36,271, dated August 26, 1862.

.To all whom it may concern:

Be it known that I, SUMNER BLODGETT, of Glover, in the county of Orleans and State of Vermont,haveinvented au Improved Machine for Wringing or Squeezing Clothes; and I do hereby declare the same to be fully described in the following specification and represented inthe accompanying drawings, of which- Figure 1 is a top View, Fig. 2 a side elevation, Fig. 3 a rear end view, and Fig. 4 a transverse section, of it, this latter being taken in a plane of the axes of the two rollers of the machine.

The nature of my invention consists in an improved clothsqueezing machine as constructedwith one elastic and one inelastic roller, and with the latter suspended in endless bearing-bands supported by pulleys, as'hereinafter specified, also, in supporting the lower or inelastic roller by means of endless suspension bands and their pulleys, in combination with springs, the whole being as hereinafter described; also, in the combination and arrangement of a tub-platform with a roller-frame and its rollers, as hereinafter specified; also, in the arrangement of adjusting-screws and their washers with the elastic rubber springs, the

forks, the endless bauds, and their pulleys as applied tothe inelastic roller.

In the said drawings, A denotes a vertical or upright frame, which is erected on a projecting platform, B, and is for the purpose of holding two rollers, G D, and their supports. The lower of the said rollers is to be an inelas tic one, or, in other words, is to be made of wood,and to have upon its shaft a two pulleys,

b b, they being arranged'outside of the frame,

as shown in the drawings. The roller shaft runs through Vertical holes or slots c c, made, respectively,in the two upright posts d d of the frame. The roller C is arranged directly over being arranged within the fork, as shown in Figs. 2, 3, andet. The shank of the fork passes upward through the top bar, L, of the frame A, and also through a spring or cylindrical y block, Z, madcof vulcanized indiarubber. The said shank also passes through a wooden washer, m, arranged ou the top of the said spring. Furthermore, the fork has a male screw, n, formed ou its upper end, and upon which is screwed a lever, o. Immediately below the lowerroller,D,are two inclined planes, H I, one of which serves to direct into a tub, when placed upon the platform B,the water or liquid when expelled from the clothes by the rollers. The said'platform B is intended to be placed upon a bench or table, and to receive upon its upper surface the tub in which the clothes are to be washed, the weight of such tub and its contents being thus made t0 operate in a manner to keep the squeezing-rollers in their due relation or position with respect to the tub.

In most other clothes-squeezers the rollerframe is provided with clamps or devices of like character for fastening it to a tub. In my improved machine such clamps are entirely dispensed with, as during their application to a tub they are very liable to mar or bruise it, and they injure its appearance.

The inelastic roller has its shaft provided with a crank, K, and is suspended, as it were, by the endless straps and pulleys from the springs arranged on the top of the frame A. On turning the crank the inelastic roller will be putin operation with very little friction, as l I its endless suspension-bands and their supporting-pulleys will be revolved by andy with it, and the springs will allow the said roller to be pressed away from the other roller while the clothe'sare being squeezed. By using an inelastic roller in conjunction with an elastic one and supporting the said inelastic roller by devices as specified, I avoida serious inconvenience, which is liable to result when two velastic rollers are employed, the same being the liability ofthe elastic covering ofthe rollers to be twisted around their shafts. Itis very difcult to apply au elastic covering of vulcanized rubber to a shaft so as to enable such rubber covering to withstand` the twist or torsion or torsion strain to which the roller may be subjected while in use. The application of the Washers and the adjustinglevers O O and the forks F F, as described, enables the pressure of the springs or their elasticforce to be either increased or diminished as circumstances may' require. I claiml. The improvedv Cloth-squeezing machine as* constructed with one elastic and one inelastic i roller, ,and with the latter suspended in endless bearing-bands supported by pulleys, as

` specified.

2. The combination and arrangement of the tub-platform B with the roller-frame A and its rollers G D, as specified.

and their Washers with thesprings, forks, end- Y less bands,and pulleys,as applied to the lower of the rollers, as set forth. j
